SANITARY AUTOMATIC CUSPIDOR.

Specification of Letters Patent.

Patented May '7, 1907.

Application filed February 19, 1906. Serial No. 301,770.

T 0 aZZ whom, it may concern.-

Be it known that I, ARTHUR PORTER, a citizen of the United States, residing at Galena, in the county of J 0 Davies and State of Illinois, have invented a new and useful Sanitary Automatic Cuspidor, of which the following is a specification.

The invention consists of a cuspidor adaptable to be set in the floors of cars, public conveyances, ships and other places where a fixed cuspidor may be desirable, and the obj set is to produce in such a cuspidor an automatically emptying device which will eX- clude drafts from the exterior of the vehicle and which cannot be clogged with debris nor rendered unsanitary by an accumulation of spittle, cigar stumps and the like.

Another object is to produce a cuspidor which may be flushed by a stream of water without removing it from the floor.

Another object is to produce a cuspidor which may be removed from its position in the floor, a suitable cap being provided to close the orifice from which it was taken.

These objects are attained by the mechanism shown in the accompanying drawings in which Figure 1 is a vertical section of the cuspidor; Fig. 2, a plan view of the gravity valve Fig. 3, a sectional view of the coupling tube; Fig. 4, a plan view of the floor collar; Fig. 5, a sectional view of said floor collar; Fig. 6, a plan View of a cap which is adapted to close said floor collar when the cuspidor is removed; Fig. 7, a sectional view of said cap; and Fig. 8, the form of wrench provided for adjusting the cuspidor into its position;

Similar letters refer to like parts through out the views.

A represents the floor, B a screwthreaded collar which is let into the floor, B is a cap which is screwed therein when the cuspidor is removed.

C is the base of the cuspidor, approximately bell-shaped and c--c are holes through the wall of the base, being provided for engagement with a wrench and also to allow warm air to penetrate to prevent the freezing of any possible moisture which may have gathered in the journals of the automatic gravity valve.

D is a receiving cup'and D a threaded tubular extension thereof, said tubular extension terminating in a chisel edged extremity (1; said tube at its junction with the receiving I cup is screw-threaded to engage similar threads in the upper part of the base C, as shown.

E is a coupling tube which extends through the floor, being held in position by screw threads which engage the threads in the collar B; said coupling tube E is provided with screw threads 6 at its upper extremity which engage corresponding threads in the base C; said tube E is of greater diameter above the 'floor than the portion which engages the floor-collar B, being also provided with an enlarged portion E which is sufiiciently recessed interiorly to accommodate the valve F out of the line of the interior diameter of the tube B to provide for the free passage of matter which may be thrown into the cuspidor.

E are lugs, of which there are two, said lugs being integrally a part of the tube E.

F is a gravity valve which automatically closes the throat of the tube D. lugs E a slot or opening is provided in. the tube E through which the closing end of the valve Fis introduced into the said tube. The rear end of the valve inclines downwardly as shown, and is slightly greater in weight than the forward part; being so adjusted insures the return of the forward part to its seat when the contents of the cuspidor have been discharged the valve is provided with pivots f which are journaled in the lugs E.

It will be observed that the tube D eX- tends into the tube E to a depth suflicient to reach the valve F. As shown in the drawings, the upper surface of the valve is dishshaped, but this is a mere detail which may be changed if found desirable.

G is the form of a wrench which is provided in two sizes for the purpose of screwing the base 0 to the coupling tube E and the tube D of the receiving cup D-into the base C, said wrench G being provided with a hooked end g to engage holes 0 of the base O and holes d of the receiving cup D lugs g g upon said wrench are designed for engagement with the holes I) b in the cap B.

In adjusting the cuspidor to the floor, the cap B is removed and the tube E is screwed into the collar D, the valve F is then placed in its bearings the base 0 is then screwed into position upon the coupling tube E; the tube D of the receiving cup D is then screwed into the upper threaded portion of the base 0. When it is desired to dispense with the Between the with the base, a valve journaled in said opening portion, the lower extremity of which cuspidor, the operation is reversed and to close the opening in the floor the cap B is inserted in the collar B.

In operation, when anything is put into the cuspidor of weight sufficient to overbalance the weighted end of the valve the forward end of the valve drops downward into the recess in the enlarged part E and the rubbish passes down through the floor; the valve then being relieved, assumes its closed position. When the valve opens its action and position are shown by dottedlines in Fig. 1.

I claim:

1. A sanitary automatic cuspidor having a coupling tube provided with a valve carrytube extends into the floor, a bell-shaped base which fits over the upper extremity of the said tube, a receiving cup having a tubular extension to engage with the upper end of the said base and with the upper end of the said coupling tube, substantially as shown.

2. In a sanitary automatic cuspidor, a coupling tube whose lower extremity passes through the floor and is secured thereto by a threaded collar, said collar being permanently secured to the floor, a base which encompasses the upper extension of the said coupling tube and rests thereon, the lower edge of said base resting upon the floor, said coupling tube having a slot or opening in one side thereof below its point of connection ing and having a weighted end which extends without said. tube and has play between said tube and base, and a receiving cup having a tubular portion which extends through the upper portion of the said base and into the said coupling tube a sufficient distance to meet the said gravity valve.

3. A sanitary automatically. emptying cuspidor, having a base portion, a receiving cup portion, said receiving cup having a downwardly extending tube portion, an automatically acting gravity valve which closes against the lower edge of said tube, a coupling tube which carries the said valve, said tube having a slot or opening therein through which the closing end of the said valve may pass into the said tube, the weighted ortion of the said valve being exterior to t e said coupling tube, an enlarged portion below the said opening recessed within the said tube for receiving the closing portion of the said valve when the valve is in an open position, said valve when in said open position being clear of the passage way through which the contents of the cuspidor'is discharged, exterior lugs upon the said coupling tube for carrying the pivots of the said valve; the said base, receiving cup extension tube and the coupling tube being adapted to be held together by screw-threaded joints.
